Overview

These intrinsics enable the AI Engine to access the input/output streams. Some of these intrinsics are "blocking" and will stall the AIE when trying to read from an empty stream, or write to a full one. Non blocking intrinsics have "_nb" in their name.

Concerning performance :

32-bit streams can be read/written every clock cycle.
128-bit streams can be read/written every 4 clock cycles.

Packet headers
These intrinsics are designed to facilitate the headers creation. They do not write directly to stream and should always be combined with a "put_ms" call.
unsigned int	packet_header (unsigned dstID, unsigned pcktType)
	Generate a packet header.

Function Documentation

◆ ctrl_packet_header()

unsigned int ctrl_packet_header	(	unsigned	Addr,
		unsigned	n_words,
		unsigned	op_type,
		unsigned	rspID
	)

Generate a control packet header.

Parameters

Addr	unsigned Local Byte Address (two LSB not used). Accesses are 128 bit aligned.
n_words	unsigned 2 bits. 1 to 4 words of 32 bit data to follow. This must be a compile time constant.
op_type	unsigned Operation modes - 2 bit (LSB). 3 modes. 0 - Write without return, 1 - Read with return, 2 - Write with return. The response to a read will be a packet switched stream header and 1 to 4 32 bit word data. The response to a write will be a packet switched stream header. This must be a compile time constant.
rspID	unsigned Response ID: 5 bit (LSB). Identifies the return destination for operation modes with a return. (The return packet's header's 'dstID' is set to this).

This intrinsic takes an address, number of words, operation type and response ID and returns a control packet header.

Note: Parameters 'n_words' and 'op_type' must be compile time constants.

Deprecated:: Please use 'void put_ms_ctrl_packet_header(int, int, unsigned, unsigned, unsigned, unsigned)' instead.

◆ packet_header()

unsigned int packet_header	(	unsigned	dstID,
		unsigned	pcktType
	)

Generate a packet header.

Parameters

dstID	unsigned 5 bit (LSB). Identifies the destination of the packet. Should be unique amongst all streams it shares ports with. Can be 32 destinations or more with nested headers.
pcktType	unsigned 3 bit (LSB). Can be used to distinguish packets with the same source and destination. Control packets set this to 7 if there is an error. This must be a compile time constant.

This intrinsic takes a destination ID and a packet type and returns a packet header.

Note: Parameter 'pcktType' must be a compile time constant.; A packet with nested headers has a number of headers at the beginning (instead of the usual single header). For every level of header nesting, the number of possible destinations is multiplied by 32, thus for a two-nested header approach, the number of destinations is already 1024.

Deprecated:: Please use 'void put_ms_packet_header(int, int, unsigned, unsigned)' instead.

◆ put_ms_ctrl_packet_header() [1/2]

void put_ms_ctrl_packet_header	(	int	idx_ms,
		int	tlast,
		unsigned	Addr,
		unsigned	n_words,
		unsigned	op_type,
		unsigned	rspID
	)

Generate a control packet header and Write to 32-bit streams.

Parameters

idx_ms	master ports
tlast	The optional tlast parameter indicates the last word in a packet and the default is false.
Addr	unsigned Local Byte Address (two LSB not used). Accesses are 128 bit aligned.
n_words	unsigned 2 bits. 1 to 4 words of 32 bit data to follow. This must be a compile time constant.
op_type	unsigned Operation modes - 2 bit (LSB). 3 modes. 0 - Write without return, 1 - Read with return, 2 - Write with return. The response to a read will be a packet switched stream header and 1 to 4 32 bit word data. The response to a write will be a packet switched stream header. This must be a compile time constant.
rspID	unsigned Response ID: 5 bit (LSB). Identifies the return destination for operation modes with a return. (The return packet's header's 'dstID' is set to this).

This intrinsic takes an address, number of words, operation type and response ID and returns a control packet header.

Note: Parameters 'n_words' and 'op_type' must be compile time constants.

◆ put_ms_ctrl_packet_header() [2/2]

void put_ms_ctrl_packet_header	(	int	idx_ms,
		unsigned	Addr,
		unsigned	n_words,
		unsigned	op_type,
		unsigned	rspID
	)

Generate a packet header and Write to 32-bit streams.

Parameters

idx_ms	master ports
tlast	The optional tlast parameter indicates the last word in a packet and the default is false.
dstID	unsigned 5 bit (LSB). Identifies the destination of the packet. Should be unique amongst all streams it shares ports with. Can be 32 destinations or more with nested headers.
pcktType	unsigned 3 bit (LSB). Can be used to distinguish packets with the same source and destination. Control packets set this to 7 if there is an error. This must be a compile time constant.

This intrinsic takes a destination ID and a packet type and returns a packet header.

Note: Parameter 'pcktType' must be a compile time constant.; A packet with nested headers has a number of headers at the beginning (instead of the usual single header). For every level of header nesting, the number of possible destinations is multiplied by 32, thus for a two-nested header approach, the number of destinations is already 1024.

void put_ms_nb	(	int	idx_ms,
		float	a
	)
